you got this

Watch our how-to video here
  1. Insert - Wash your hands and the FLEX Cup for 20 seconds. Press the sides of the cup together and then fold it in half again forming a tight ‘U’ shape. OR place a finger on the top rim of the cup and press it down into the center making the top smaller for insertion. Get in a comfortable position, relax your vaginal muscles, insert the FLEX Cup into your vagina, sliding it up and back toward your tailbone (not straight up).
  2. Wear it for up to 12 hours.
  3. Remove - Simply pull the ReleaseRing™ to break the seal and remove. The ReleaseRing™ pulls the top of the cup in to break the seal and help prevent spillage during removal. Before using or reusing, remove the ReleaseRing™ and thoroughly wash the cup for 20 seconds with warm water.

Are you afraid to try it? We totally get it, trying something new can be challenging but once you nailed it, your period will never be the same. If you need help, our team of amazing FLEXperts are here for you at hello@flexfits.com

I am 42, have a really heavy flow and would leak through Super Plus tampons, my underwear/jeans /bed sheets every hour. My sister recommended that I give a cup a try, she has the same issue, but was going back on the pill. I've used tampons for probably 25 years and was recently having to use Thinx as a backup. She sent me some influencers "cupdate" video and this was among the top two. I ordered the larger one and it came rather quickly. I loved the little carry bag and couldn't wait for my period to start! I will say that it's definitely trial and error at first, but don't give up!! I am so used to it now, that I will NEVER use another tampon again. I still cramp like I always have, but my periods are shorter. I had a few leaks in the beginning, questionable insertion, but now I'm back to not wearing any underwear while on my period. It's been about 7 cycles now, and sometimes I have really long acrylic nails and you can still put it in and take it out with ease! I don't even notice that it's in there, nor do I feel/see the tab. This paid for itself after two cycles because I was buying a 50 pack every time. The only thing that I haven't done is try the discs that came with it or gone swimming (yet). I am always telling people that they should try it, I love it that much! THANK YOU

The best thing to ever happen to my period.

I've been using a cup for years and preach it to everyone I know - but when I saw an ad for Flexcup I jumped on it immediately because, let's face it, sometimes taking it out is not so easy. This cup has changed my life. Not only do I not have to worry about leaks or changing a tampon constantly, the removal process is easy and painless. I'm seriously stunned. I will say that it's a but stiffer than my last cup so inserting (size small) took some getting used to, but overall it's a fantastic product. And the packaging is GORGEOUS. Highly recommend. Already have, actually, to several friends .

Only thing I'll use from here on out!

Flexcup was my first period cup and it'll also be my last. I'm never going to use anything other than this device. Even on my worst days it makes life so much easier. Absolutely ZERO leaks. No discomfort or insecurities. I was skeptical on the flexcup game but I have to tell you this is the real deal!

I am in aw of this product!

I had never before tried a menstrual cup, and I am so happy I got Flex! This has changed my period completely! It has even happened that I forget that I am on my period while wearing the Flex cup. This is a miracle product, and I am so thankful! I am grateful to have something that is sustainable and not potentially harmful to my body! Thank you!!

FANTASTIC cup for a high cervix !

I never write reviews but I had to write one for this product.

I have tried 4 cups which are on the market, but they've never been a success as I have a super high cervix. This means I have always found removal tricky as cups would migrate far up, and no matter how much I would bear down, pinching the base for removal would be incredibly diffcult. I have had many stressful times in my bathroom over this!

HOWEVER.... the Flexcup is an actual gamechanger. I insert it using the 7 fold, which I find easiest as it pops out nicely once in. The cup is comfortable, the tab can't be felt and I've had no leaks.

When it comes to removal, it's ridiculously easy, just pull the tab to break the seal and move the cup down until its down far enough to grab the base. I honestly can't recommend it enough for any one with a high cervix struggling to find a cup thats right for them. I wish I had found this one first! I am so happy I found this, and can now use a sustainable period product.

I'm hoping that they will be stocking these on their UK website soon so that I can buy a backup cup, as I had to pay for international postage. But honestly it was worth it! ;)

Try FLEX with some liners at first.

Sometimes you just feel better with a little backup. FLEX plus liners would be a great combination for you while you transition to FLEX to help guard against leaks until you get the hang of positioning FLEX.
